Soundcloud has offices in London. They just opened up a new office in SF recently as well. But you're right in that their main HQ is definitely in Berlin, although were originally founded in Sweden!
Sorry to say this, but it sounds pitiful when the final line of your number 1 startup is "even attracting attention and investment from Hollywood bigwigs such as Madonna’s manager Guy Oseary and Ashton Kutcher."
That said, I'll be in Berlin this weekend to check out the scene.
Also there is a huge split in between the copy-cat businesses usually operated by the samwer brothers and the next generation startups like soundcloud, 6wunderkinder, wooga and others.
I was thinking the exact same thing while reading this. Wunderkinder is missing and the majority of these companies are copy-cat businesses. Granted, Wunderlist is a to do app which there isn't a shortage of, but they've managed to keep their product free while maintaining cloud sync, great UI, and relevance among its productivity community. Meanwhile they opted to include a general "rebate networks" and deal network companies. This is my long-winded way of saying this list is mediocre and Wunderkinder deserves to be on a list like this.
Just checking out Wunderkinder for the first time. Thanks for passing it along. I've never heard of most of these companies before, but I'm glad to see something other than SanFran startups.
For the record all their jobs are in Berlin so score 1 for the Germans and -1 for british journalism :-) http://soundcloud.com/jobs
